Be it known that l, ARTHUR lll. SriNAssn, a citizen ot' the UnitedStates, residing at Mount Vernon, in the county of lino); and State otUhio, have invented certain new and useful Improvements in VApparatusfor Drawing Glass Cylinders; and l do hereby declare the following to bea lull, clear and exact description oit the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

'lhe invention relates to new and useful improvements in an apparatustor drawing1 glass cylinders, and has for an obj ect tom provide meanswhereby a single motor may be utilized for operating the drawing meansfor drawing the cylinder, and also the gem erating means for generatingair for the formation of the cylinder, whereby any variations in thespeed of the motor, thus valying` the speed of draw, will likewise varythe amount of air supplied to the drawing means.

A kfurther object of the invention is to provide means whereby the speedot the motor may be regulated.

A still further object oit the invention is to provide means whereby theregulation of the speed ot the motor is controlled by the position ofthe bait of the drawing means to which the cylinder is attached.

These and other objects will in part be obvious and will in part behereinafter more iully disclosed.

showingl an attachment of an injection jet t'or blowing 'the cylinder.

ln these drawings like letters of reference indicate lilre parts. l lpreferably use two jointedL or articulated arms or pipe sections 1 and2, oit' about equal length, and each slightly longer than one-fourth ofthe length of the article or cylinder to be drawn. Une oi these arms,which is the iinal end of the air conduit, is plvoted, as at 3, to thecarriage 1, which slides upon the uprights 5 in the production ot' thecylinder.

rlhe sign 6 represents a winding` drinn around which is wound the ropeor cable 52, the other ond of which is attached to the drawing carriage.At i occurs the iii-st joint in my articulated pipe. This joint occursbetween one section o1- the articulation and a lined part of the pipe,and is tl'iere- 'fore a fixed joint. rllhis joint corresponds in somerespects to the shoulder joint ot the human arm, and the joint 3 to thewrist joint. Between these joints is the joint 23, which corresponds tothe elbow joint ot' the arm.

The shoulder joint 7 is located about half way up the traverse ot thedrawing,` carriage, so that while the joint 3 is passing from its lowestto its highest point, the two members 1 and 2 will be swung' about theirpivots 28 and 7i. rlFhese joints are always ilree and open, as shown inFig. 4t particu lai-ly, for the t'ree passage of air.

The upper member ot the articulation l l preferably extend inA an arm 8,through which air may not pass. This arm or level' extension 8 isadapted to move over the contact points or' the adjustable rhcostat 9which is in the shunt lield 11 of a motor 10.

At 12 l provide a reversing` switch, which is in the armature circuit,so that the motor can be reversed, if desired, for lowering thecarriage. rldhe load is ontrolled by the rheostat 13 in the samecircuit, said rheostat also serving` as a switch. l connect the motor 10by means o'l. clutch 14 to shalt 15, and this, by means ot `fears 16,17, 18, the last ot which is a worm gear, to the drum 6.

At 19 l show the projecting1 nipple of the blowing apparatus, adapted toblow air into the upper part ot the bait 20, shown in lFig. 1 as in theact oi starting,1 cylinder 21 from the bath 2:2, which may be containedin any suitable receptacle, The bait may be, of

-the operator Vfor eoai'seadjnstment.

course, connected in any suitable manner. I continue the members 1 and 2in the conduit 24 connected to the blower 25.

The effect of the blower is to i`eed air toward the cylinder bei-ngformed, beyond the capacity or' the cylinder, and the surplus-air thusied is taken oif by the controlling valves 26 and 54, which are arrangedto be under the control of the operator. yThe overiiow or Valve 26 isarranged to be quickly turned1` ie valve 54 is used only for tineadjustment by means of the screw 56, the connecting rod adjustable uponthe-arm or valve 54, and the wheel 57. rlhe operator thus has the airunder tine control, and can regulate the pressure down to a nicety. I

It 'motor'lOshould get out of order it is disconnected yat clutch 14,and by means of clutch 27 the auxiliary or siuppleiiientary motor 28 isbroughtinto use.

.In Fig. 2 is r`shown, in front view, the winding drum 6, and vinvconnection with this vdrum I may provide a clutch 30, operated by arm31 pivoted to some iiXed point, and to wh-ich may `be y'connected cable33 which extends somewhere within the reach of the operator, so that bypulling cable 33 the arm 31 is swung against spring 32 to disconnectclutch '-30 from the drum, whereby the drum becomes loose on shaft 32and the carriage is permitted to rapidly lower itself until it cornesnear the level oi' the glass, where it -is stopped, abait 58 attached toit Aand the switch 1.2 swung` to give the motor downward motion untilthe bait becomes inimersed to a suiiicient depth in the body of themolten glass. The motion is then stopped, and the direction reversed byreversing the switch, and the drawing then proceeds. The

yrheostat .13 is adjusted and the valves 26 and 54 looked ater;- therheostat 9 ybeing automatically responsive to the position of the parts1 and 35, which in turn is responsive to the position oi' the drawingcarriage.

.By introducing greater vor less resistance into the motor field, Idetermrne'the speed of the draw and the speed of the blower as well.

cylinder is thenl severed at the bottom and taken down in the usual way.The arm 1 may begin t-o oscillate as soon as the draw begins. I do notwish tol change the speed of drawat this early stage. I thereforeprovide in my-rheostat 9 a lengthenedcontact '29, so that while the arm8 is switching over this contact the resistance in the field coils ofthe motor, and consequently the speed of the motor, is not changed. Y Inconsequence,

for initial period of the draw, the drawing speed, and the blower speedand generated aii pressure remain constant.

The pipes 1 and 2 may be provided with a pivot at 7, which may havesuitable adjustment either vertically or horizontally. The

rheostat itself is adjustable.

My rheostat is adjusted or graduated so as togive a prescribed speedover a certain distance of draw, and generate air in desired quantityfor a certain distance or period of the drawing. A change may take placein the speed and the draw over 3Q, 40 or inches, more or less, as may bedesired. The air pressure generated is ail'ected accordingly, or insynchronism with the change in the drawing speed. I have shown the airand speed varied together by one set of arms 1 and 2, but I may providemeans for varying them independently.

InFig. (i I show my preferred i'oi'ni ot rheostat 9. As above stated,connected to the pipe 1 is an extension S, which is the Contact arm ofthe rheostat. This I provide with the shoe which travels upon thecontacts 29, 36, 3T, 38, $39, 4() and 41. I do not sho'w 29 in Fig. (S.irlthough, of course, the contacts may be of any number and ot anyproportionate size, each represents so inany units oia length of thecylinder being drawn.

I provide tor each contact an extension 44, shown inthe contact 3, andin this extension `is a slot 42 through which, by nieans of a screw,each contact is secured to the board 43. These contacts may be arrangedin any of the known ways lfor arranging them on rheostats.

In the i'heostat here shown, cach oli the live contacts rcpreseiits acertain part ol the cylinder drawn. By this means each part of thecylinder can be referred to a certain part of' the rheostat, and, shouldnecessity for changing speed or generated air pressure arise, asletcrinined troni an inspection of the cylinder, the contacts ot therheostat can be-arranged accordingly. Thus the sections numbered 1, 2,3, and so on of the rheostat, correspond with the lirst. second, third,etc., sections of the cylinder.

In Fig. G the dotted line 45 shows the pipe 1 nearly at the end ot anope ation. The shoe 35 is near the end of the rheostat, and the contact41, the iinal contact, may be adjusted so as to automatic: llydisconnect beyond a certain point.

Each contact is inserted into thc iield as follows:

46 represents a resistance coil with a succession of buttons 59, asshown. The wire 47 is from contact. 3G to the first button ot the coil.Therefore the shunt lield circuit. is normal. lVhen shoe 35 reachesconlact 37 it cuts in six buttons ot the resistance coil through thewire 49, 4S. Similarly. more resistance may be cut in as the shoe pro lI) (l ceeds. By the device arranged as shown, the rate of speedincreases successively for each length up to length l, and then it maysuddenly drop to normal at the iitth length. The rheostat is set todraw, say, a tour length cylinder, each contact correspomiling to a onelength cylinder. @t course this may be varied. Therefore when contact 5is reached the speed is reduced to normal; this T indicate by dottedline 50. At this slow speed the lower part oi? the cylinder' isseparated from the glass bath either by lire or by breaking in wellknown manner; then more current may be added, or another contact causingthe motor to jump to higher speed, may be provided to further elevatethe cylinder away from the glass bath pre paratory to taking down thesame for iurther treatment.

My automatic rheostat 9, Figs. l and 6, varies the speed of motor 10,and the speed of draw may therefore be infinitely varied at any stage ofthe draw; and since the drawing motor solely also actuates the airgenerator the air pressure generated is always correspondingly variedwith the draw subject, when they are used, to the controlling valves 26and 5l. The motor l0 is also under the control ot' the switch rheostat13. Of course in cutting in resistance into the shunt held circuit oit'motor l0, its speed is increased.

l aim to lower the speed of draw; this is oi? utility in severing thecylinder'. Sometimes the working nature of the molten glass from whichthe glass is heilig drawn may vary in such a way that, gradual decreasein the speed of draw is of great utility in maintaining even strength ofwall iu the article drawn, and other desired results, especially whendrawing is made from a glass tank.

ln Fig. l0 T show a iront view of carriage 4l with the parts inposition. This carriage slides upon the standards 5. T show pipe 2joined to pipe 6d, and this latter pipe is secured to the carriage. Theangled pipe 65 is mounted to slide to the right or lett on the carriage,and mounted to swing also in or out from the carriage. It maintainsalways a telescopic connection with the pipe 64 through which the airenters. T provide at the point 66, Fig. 8, a screw attached to thispipe, and this forms one of the means ot' support `tor said pipe, theother being the pipe 64. By turning the wheel 67', which is providedwith a nut for said screw, T may advance or retract the screw 66, andthusadvance or retract the angled pipe 65 with rei erence to pipe 64.'This screw performs another function, moreover, since it enables me toadjust the position of the bait to the right or lett of the carriage bymoving the said screw. I need not necessarily make the said telescopicconnection tight. The joint formed by pipes 64 and 65 may, however, bemade to operate iiush so as to prevent the escape of the air.

T provide at 69 and 70 shoes which engage with the standards 5, andthese shoes are pivcted to one end of bent levers 7l mounted upon thecarriage. The other end ot each oi? these levers is connected to aretractile spring 72, as shown, sothat the tension ot the spring 72 hasa constant tendency to push the shoes 69 and 7() against the part 63 orslideway. The carriage is thus always held in lirm relation to itssliding ways and does not chatter nor stick.

rit 73 l. show a bent portion of the angled pipe 65, in which portion Tmount the upper part oi" a bait. This bait is mounted simply bythrusting its upperend into the part or expansion 73. At Te T show ascrew mounted in the carriage and adapted to contact with the part 65,above alluded to, of the pivoted angled pipe. By turning this screw T amenabled before drawing, quickly to adjust the position of the bait 58 toand from the carriage. This, taken in connection with the adjustmentprovided by the screw 66, gives me means for adjusting the bait at anypoint desired, within a given area. T show attached to the bait properin these figures, a hook or loop 75 to which atool may be attached toaid in handling` the bait.

li-n F 10 l show a modified way oi attaching the bait, the drawingcarriage being supplied simply with the entering pipe 64:, iu the mouthof which is pivoted the horizontally turned upper end of the bait.

ln F il T show another modilication in which the pipe 6d terminates in adownwardly extending jet 68, which discharges directly into the flaringupper end 67 .ot the baits handle. ln this form oit device air should besupplied in greater quantity than in the other, because the overflow, atthe jet 68 and end 67, of air is apt to be greater than in other `terms;at the same time a certain uniformity is attained in this constructionwhich is not always possible in other constructions. The bait is hereshown attached directly to the carriage in the fork 69.

Ido not wish to be limited to the precise construction shown, but desireto have my invention cover all equivalents.

'T he drum and machinery may be to one side the glass, so as to avoiddirt Y[falling in the glass. They may be located at a point remote, andthe cable held in position by means ot a suitable wheel.

The rheostat also is preferably inclosed so as to avoid deposit ot dustupon the contact which would have a tendency to aliect their operationinjuriously.

From valve 54, to the carriage, bait, or rheostat, l may increase thelength ot my air pipes, as per A and P, tor the tcllowing reason:

rAir is elastic, it is well known, and I take Aadvantage of thisphysical property by lengthening the air conduit,since the elasticeffect of the y.air increases in proportion to the length of the pipe,Land therefore the nicer the effect of the same to the article formedthereby.

It will be seen that by my structure I am enabled'to govern the speedand draw in direct response .to the position of the bait as itapproaches the upper end of the draw. I place the air supply also incontrolled relationto theposition of the bait because it is driven bythe same motor that drives the bait. It is to be observed, however, thatthe `air pressure is not always indirect response to the speed ofrotation of the fan absolutely. Hence'Ifind it necessary, at certainperiods of the draw, to provide means for varyinO` the-air supply in thevalves 26 and 54. l oreover, these same valves provide means for varyingthe air supply in response to occasional conditions of the glass,particularly conditions of viscidity induced by some slight variation inthe formula to which the batch is composed, or variations oftemperature, weather, etc. That is, I provide a device which, as long asthe conditions remain absolutely --unchanged, automatically operates;and at l,the same time I provide means whereby the functioning of thisdevice may vbe controlled or immediately changed to meet special needs.

I have, it will be noted, provided a single motor effecting draw andsupplying air. The speed oi thismotor must necessarily be reduced bysuitable reducing gear, to the requirements of the draw, and incordinating the pressure and supply of air to the draw when. both comefrom a rapidly moving motor, I effect a desirable smoothness ofoperation. To cut down the two simultaneously reduces variation in thecylinder drawn.

In my rheostat 9 I also provide means for ychanging the speed ofthe'motor, and consequently therate of draw, to meetvarying conditions.

The invention in its broadest aspect is directed to a motor togetherwith means operated thereby for drawing the cylinder, and a blower whichis also connected to the motor so that both the drawing lmeans and theblower are operated by one and the same motor, whereby variations in thespeed of the motor will affect the speed of draw, and likewise affectthe amount of. air supplied for drawing purposes, and so far as thisaspect of the invention is concerned, the control of the motor may behand controlled instead of automatic. The invention is further directedto controlling means for regulating the speed of the motor, and in itsmore specific aspect, to the control of the speed by the movement of thebait during the drawing of the cylinder.
